Subject [jira] [Commented] (YARN-6003) yarn-ui build failure caused by debug 2.4.0
Date Fri, 16 Dec 2016 08:25:58 GMT

    [ https://issues.apache.org/jira/browse/YARN-6003?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15753808#comment-15753808
] 

Sreenath Somarajapuram commented on YARN-6003:
----------------------------------------------

It because npm uses semantic versioning (semver) rules and the dependencies are not locked.
Semver relies on package developers to not making mistakes, and here we stumbled upon a package
with a bug.
Best option to fix this issue would to move to yarn package manager instead of npm. It also
comes with added advantages like faster build time & offline build support.
A patch for the same is under investigation.

> build@2.4.0 is broken. https://github.com/visionmedia/debug/issues/347
> Maybe we need to set the version to 2.4.1 explicitly.
